中文摘要:
      蓄热式电采暖作为一种电能替代技术,在应用的过程中会给配电网的安全运行带来影响,随着人们对分布式能源的重视和电采暖相关技术的发展,电采暖的研究愈发重要。为了充分挖掘蓄热式电采暖在配电网中的可调节潜力,从蓄热式电采暖单体和集群两个层面进行分析。首先提出可调节潜力量化指标,包括容量、充放电功率、储能状态、上调容量和下调容量;接着分析蓄热式电采暖单体可调节潜力指标的数学模型;然后利用模糊聚类算法基于用户的用能特性,对电采暖用户进行聚类,分析蓄热式电采暖集群的上调容量和下调容量;最后通过具体算例对数学模型进行验证。
英文摘要:
      As an electric energy alternative technology, regenerative electric heating will affect the safe operation of the distribution network in the process of application, with people’s attention to distributed energy resources and the development of electric heating related technologies, the research of electric heating is becoming more and more important. In order to fully exploit the adjustable potential of regenerative electric heating in the distribution network, the analysis is carried out from the two levels of regenerative electric heating unit and cluster. Firstly, the quantitative indicator of adjustable potential is proposed, including capacity, charge and discharge power, energy storage status, up-regulation capacity and down-adjustment capacity. Then the mathematical model of the adjustable potential indicators of regenerative electric heating units is analyzed. And then fuzzy clustering algorithm is used to cluster electric heating users based on the energy consumption characteristics of users, and the upward adjustment capacity and downward adjustment capacity of electric heating clusters are analyzed. Finally,the mathematical model is verified by specific examples.
